- 摘要:
- 运载火箭总体方案论证阶段，为了选择推进系统方案需要对发动机的质量、性能等参数进行比较和优化，但是液体火箭发动机的质量是很难估算的，影响发动机质量的因素很多，几乎没有什么规律可循，估算发动机质量的工作只能是非常粗糙的。依据液体火箭发动机主要部件的特点及工程经验，提出了发动机核心部件的质量计算模型；给出了发动机推力室和涡轮泵2部件的2种计算模型并进行了比较。最后，采用VC++平台设计了可视化的计算界面，并结合国内外的发动机进行了验证。
- Abstract:
- At the beginning of project development of a new aerospace launch vehicle, in order to choose the design scheme of propulsion system, it's necessary to contrast and optimize the rocket's parameters, such as mass and performance. However, it's difficult to calculate the mass of a liquid propellant rocket engine duo to more related factors, because there is nearly no rule to follow, so the mass evaluation of a liquid propellant rocket engine is usually not precise. According to the characteristics of the liquid propellant rocket engine and project experiences, the mass calculation models for the key assembly units of the engine are proposed in this paper. Two kinds of different models to calculate the mass of thrust chamber and turbopump are presented and compared. At last, based on the VC++ platform, the visual interface was designed for the mass calculation model. The mass models were validated by the calculation of different kinds of liquid propellant rocket engines.
